LOUIS YOUNG, OFv NEJV YORK,

REVOLVING MEASURING-WHEEL.

Specification of Letters Patent No To all whom it may concern.-

Be it known that I, LOUIS YOUNG, of New York, in the county and State ofNew York, have invented a new and useful Revolving Measure; and I dohereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being hadto the annexed drawings, making a part of this specification, and to theletters of reference marked thereon.

Figure I is a longitudinal section of the measure. Fig. II, is anoutside view of the same with the cap removed. Fig. III, is a top viewof the same. Figs. IV, V, and VI, are inside, outside, and top views ofa revolving measure, with some modifications and Fig. VII is a view ofthe cap (2').

(a) is a wheel six inches on its circumference and divided in inches andparts of inches on its face, attached to an axis (71), turning freely inthe casing (A). On one or both ends of the axis (71) a small eccentriois attached and connected through the rod or rods (17.) with the slide(cl), sliding in suitable grooves in the casing (A). To this slide (cl)a lever (m) is fastened which works into teeth on. the circumference ofa wheel (B). By this arrangement every revolution of the wheel (a), thewheel (B) is turned the distance of one toot-h around.

(79) is a small spring acting upon the lever (m) to insure always, evenby a quick motion, the falling in of said lever (m) into every tooth ofthe wheel (B).

(as) is a spring catch, to hold the wheel (B) and prevent anypossibility of the same turning back while the lever (m) moves from onetooth to the next following.

(w) (Figs. I, II and III) is a cover made in the casing (A) to be ableto get at the wheel (B) to turn the same by hand when required. Thewheel (B) has on its face divisions corresponding with the teeth on itscircumference, which said divisions are numbered and can be seen throughan opening (C) in the side of the casing (A). The circumference of thewheel (a), if as before mentioned, is made six inches, will by eachrevolution turn the wheel (B) one tooth around, consequently each of thedivisions on the face of the wheel (B) will show six inches, and thenumber of feet and inches 13,833, dated November 20, 1855.

which can be measured by any instrument depends therefore upon the sizeof the wheel (B). If any very great length is required to be measured asmall wheel can be placed on one side of the axis (Q) of the wheel (B)working into a larger index wheel by which the number of feet capable ofbeing measured at one time can be extended to several hundred feet,without the possibility of any mistakes occurring. To use this revolvingmeasure turn the wheel (a) so that the pointer (9) attached to thecasing (A) corresponds with the division marked (0) on said wheel, thenopen the cover (20) and turn the wheel (B) that the division marked (0)thereon, corresponds with the lower edge of the opening (O) in the sideof the casing (A) as represented in the drawings.

Then place the instrument upon the substance to be measured, so that thedivision (0) of the wheel (64) comes to the edge of the substance, androll the instrument over the same, when the number of feet and half feetcan be read off the wheel (B) through the opening (O), and the remaininginches and parts of inches, of the wheel Before measuring again anyother substance the wheel (a) and wheel (B) must always first be turnedaround in the manner and into the position above mentioned, so that thedivisions marked (0) correspond with the pointer (g) and the edge of theopening To prevent this inconvenience a spi ral spring (L) (Figs. IV, Vand VI) can be placed in the center of the wheel (B) to bring the samealways in the required position, before measuring any new substance. Aprojection ((1) being in that case attached to the whel (B) as well as apro jection (f) on the casing (A) to stop the wheel in its rightposition. A small lever (1') is in that case introduced between thecasing and worked on the outside by a small handle or knob (K),and-arranged in such a manner as to act upon the lever (m) and the catchspring (00) so as to throw both out ofi the teeth on the wheel (B), toallow the spiral spring (L) to turn said wheel (B). I do not confinemyself making the circumference of the wheel (a) exactly six inches asabove mentioned, but the same may be made, one, two, three, four, or sixinches according to the size of the instrument.

I do notclaim the manner of transmitting such a manner that said box ismade to serve the motion from the measurlng Wheel as a convenlent handlefor Working the to the counting Wheel (B), but instrument.

I claim LOUIS YOUNG. 5 The arrangement of the box containing Witnesses:
